Hello Gang,
I am sorry to come back to that question.
There are a few things that are not clear yet on my side.
Here is the last update of the script:
3dLME -prefix 3dLME_glt.nii.gz -jobs 20 -mask brainmask_nolr_func.nii.gz \
-model "Sexe*age" -qVars "age" -ranEff "~1+age" -num_glt 4 \
-gltLabel 1 "05MF" -gltCode 1 "Sexe : 0.5*M +0.5*F age :" \
-gltLabel 2 "1MF" -gltCode 2 "Sexe : 1*M -1*F age :" \
-gltLabel 3 "1MF" -gltCode 3 "Sexe : 1*M age :" \
-gltLabel 4 "1F" -gltCode 4 "Sexe : 1*F age :" \
-dataTable @disign_matrix.txt -resid resid.nii.gz
disign_matrix look like
Subj age Sexe InputFile
Oliver 1128.0 M Oliver2019_02_02_correlations_fish.nii.gz
Oliver 1247.0 M Oliver2019_06_01_correlations_fish.nii.gz
Pickle 1065.0 M Pickle2019_02_02_correlations_fish.nii.gz
Pickle 1184.0 M Pickle2019_06_01_correlations_fish.nii.gz
etc...
Here is the subrick obtained with the previous script after "3dinfo -verb"
-- At sub-brick #0 '(Intercept) F' datum type is float
statcode = fift; statpar = 1 53
-- At sub-brick #1 'Sexe F' datum type is float
statcode = fift; statpar = 1 6
-- At sub-brick #2 'age F' datum type is float
statcode = fift; statpar = 1 53
-- At sub-brick #3 'Sexe:age F' datum type is float
statcode = fift; statpar = 1 53
-- At sub-brick #4 '05MF' datum type is float
-- At sub-brick #5 '05MF Z' datum type is float
statcode = fizt
-- At sub-brick #6 '1MF' datum type is float
-- At sub-brick #7 '1MF Z' datum type is float
statcode = fizt
-- At sub-brick #8 '1MF' datum type is float
-- At sub-brick #9 '1MF Z' datum type is float
statcode = fizt
-- At sub-brick #10 '1F' datum type is float
-- At sub-brick #11 '1F Z' datum type is float
statcode = fizt
sub-brick 4, 6, 8, 10 are empty, is there a problem with "Sexe"? Am I supposed to use 0 and 1?
Just to be 100% sure, if I want to measure the overall age effect controlling for gender I just have to use subrick 4 and 5?
and then apply:
3dFWHMx
and
3dClustSim
Thank you!
Clément
